Bounces
Not all bounces are the same. Migma breaks them down into three types: Permanent — the email address or domain does not exist. Remove these from your list immediately. Migma adds them to your suppression list automatically so you never send to them again. Transient — a temporary issue like a full mailbox or a server being down. These can be retried. Undetermined — the reason is unclear. Keep an eye on these as they can become permanent over time.Complaints
When someone marks your email as spam, Migma records it as a complaint, adds that address to your suppression list, and updates your complaint rate.What to watch for
Delivery rate drops suddenly
Delivery rate drops suddenly
A sudden drop usually means list quality issues, bad addresses, or a reputation problem. Check your bounce logs and review any recent list imports if delivery falls below 95%.
Complaint rate climbing
Complaint rate climbing
This is the most important metric for deliverability. Below 0.05% is excellent. Between 0.1% and 0.3% is a warning. Above 0.3% is critical and puts your domain at risk. Review your email content and clean your list if complaints spike.
Open rate declining over time
Open rate declining over time
Declining opens can mean your subject lines need work, you are sending too often, or your list is fatigued. It can also mean emails are going to spam. Try different subject lines and check whether delivery rate is still healthy.
